Abstract
A method for triggering an aspect of a handover evaluation procedure in a wireless telecommunications system for determining whether to handover a terminal device from communicating with a first network infrastructure element associated with a first communication cell to communicating with a second network infrastructure element associated with a second communication cell.
Claims16
A method for triggering part of a handover evaluation procedure for determining whether to handover a terminal device from communicating with a first network infrastructure element associated with a first communication cell to communicating with a second network infrastructure element associated with a second communication cell in a wireless telecommunications system, wherein the first communication cell comprises a group of intermediate nodes distributed through the first communication cell, wherein communications between the first network infrastructure element and the terminal device are made via a subset of the intermediate nodes, the subset comprising one or more of the intermediate nodes selected as active intermediate nodes for the terminal device based on a location of the terminal device within the first communication cell, and wherein the method comprises:
- determining if the subset of active intermediate nodes for the terminal device includes one or more intermediate nodes in a predefined subset of intermediate nodes, and if so initiating the part of the handover evaluation procedure.

A method of operating a terminal device in a wireless telecommunications system to determine whether to trigger part of a handover evaluation procedure for determining whether to handover the terminal device from communicating with a first network infrastructure element associated with a first communication cell in the wireless telecommunications network to communicating with a second network infrastructure element associated with a second communication cell in the wireless telecommunications system, wherein the first communication cell comprises a group of intermediate nodes distributed through the first communication cell, wherein communications between the first network infrastructure element and the terminal device are made via a subset of the intermediate nodes, the subset comprising one or more of the intermediate nodes selected as active intermediate nodes for the terminal device based on a location of the terminal device within the first communication cell, and wherein the method comprises:
- the terminal device determining if the subset of active intermediate nodes for the terminal device includes one or more intermediate nodes in a predefined subset of intermediate nodes, and if so initiating the part of the handover evaluation procedure.
A terminal device for use in a wireless telecommunications system comprising the terminal device, a first network infrastructure element associated with a first communication cell and a second network infrastructure element associated with a second communication cell, wherein the first communication cell comprises a group of intermediate nodes distributed through the first communication cell and wherein the terminal device is configured to communicate with the first network infrastructure via a subset of the intermediate nodes, the subset comprising one or more of the intermediate nodes selected as active intermediate nodes for the terminal device based on a location of the terminal device within the first communication cell, wherein the terminal device comprises a controller unit and a transceiver unit configured such that the terminal device is operable to determine if the subset of active intermediate nodes for the terminal device includes one or more intermediate nodes in a predefined subset of intermediate nodes, and if so initiate part of a handover evaluation procedure for determining whether to handover the terminal device from communicating with the first network infrastructure element to communicating with the second network infrastructure element.
